An odor eliminating toilet seat has a lumen in pneumatic communication with the interior environment of a toilet bowl via a plurality of apertures disposed about the interior edge of the toilet seat. A fan draws air in through the plurality of apertures and over a replaceable carbon filter before permitting the cleaned air to exit the back of the toilet seat.

A sanitary washing device includes a nozzle, a valve unit, a casing, a water supply hose, and a water supply connection part. The nozzle is configured to discharge water toward an ano-genital region. The valve unit is provided on a pipe line between a water supply source and the nozzle. The casing stores the nozzle and the valve unit. The water supply hose is flexible and configured to supply water from the water supply source into the casing. The water supply connection part connects the water supply hose and the valve unit. The water supply connection part is open in a horizontal direction. The water supply hose is directly connected to the water supply connection part in a horizontal direction. The casing includes a hose container in which a portion of the water supply hose can be stored by bending.

A toilet system includes: a toilet seat; a sensor configured to measure a physical quantity which reflects blood flow conditions of a user; a health index calculator configured to calculate a plurality of health indices based on measurement results of the sensor; a health index output part configured to output the plurality of health indices which has been calculated; a timer configured to measure a seating time; and a controller configured to control an output manner of the health index output part based on measurement results of the timer. When the seating time is not shorter than a first required time but shorter than a second required time, the first health index is outputted, but the second health index is stopped to be outputted. When the seating time is not shorter than the second required time, both the first health index and the second health index are outputted.

A toilet system includes: a toilet seat having a seat surface on which a user is to sit; a sensor provided in or on the toilet seat, configured to measure a physical quantity which reflects blood flow conditions of the user; a health index calculator configured to calculate a health index of the user based on measurement results of the sensor; a health index output part configured to output the health index of the user which has been calculated by the health index calculator; a temperature determining part configured to determine whether a temperature state of the seat surface satisfies a predetermined condition or not, and an operation change instruction part configured to change an operation of the health index calculator and/or an operation of the health index output part when the temperature determining part determines that the temperature state of the seat surface satisfies the predetermined condition.

Disclosed herein is a washing and drying nozzle device for a sanitary toilet seat cover. The washing and drying nozzle device includes: a toilet seat-cover device including a support frame configured such that a cover member and a seat are rotatably coupled thereto and a sensor unit configured to detect the presence of a foreign material is mounted on the front portion thereof; a drying nozzle coupled to the support frame, and configured to dry a user's washed body by spraying air toward the user's body and to radiate far-infrared rays toward the user's body; a washing nozzle coupled to the support frame, and configured to spray water toward the user's body; a nozzle driving means installed in the support frame, and configured to slide and rotate the drying nozzle and the washing nozzle; and a control unit configured to control the driving of the nozzle driving means.

A method for controlling a toilet air heating device includes: in response to a start instruction, controlling an air heating wire component to heat, controlling an air heating fan to blow air, controlling a drive motor to drive an internal air duct to extend out along an extension direction of an external air duct, and controlling an auxiliary heater to heat, wherein an air heating wire component controller controls the air heating wire component while a master controller controls the air heating fan, the drive motor, and the auxiliary heater.

Among others, the present invention provides toilet seat assemblies for cleaning, disinfecting, and/or sanitizing toilet seat, each including a base configured to be secured to the top surface of the toilet bowl; a toilet seat attached to the base and movable between an open position and a closed position; and a cover attached to the base and movable between an open position and a closed position. The toilet seat assembly may include a liquid discharge and disperse means, which further includes one or more liquid discharge apertures for discharging a liquid, particularly with an atomizer for spraying the mist, and one or more gas discharge apertures for facilitating dispersal of the liquid, thereby enabling the liquid to contact, clean, disinfect and/or sanitize the toilet seat.

Toilet seat cleaning devices, methods and systems are described. Toilet seat cleaning systems may include a toilet, a toilet seat, a sensor, and a fluid dispenser. Toilet seats may include a flow way, at least one opening and at least one surface whereon fluids from a fluid dispenser may be communicated. Fluid dispensers may include a fluid container and a dispenser mechanism. Methods of using toilet seat cleaning systems may include a user influencing the activation of a dispenser mechanism; the dispenser mechanism influencing the communication of fluid from a fluid container to a flow way; the fluid being communicated through the flow way and out of at least one opening and onto at least one surface of a toilet seat; and the fluid on the at least one surface of the toilet seat being engaged by the user in order to clean the toilet seat.

A plurality of color sensing sections are attached to a toilet seat so as to test a health state or a fecal occult blood portion every time by capturing the feces surface color during defecation. Before feces which have been excreted from a body sink into a water-seal portion, the circumference of the feces is optically captured to detect the color of the surface of the feces. By monitoring changes in color, the health state of the defecator is monitored. In particular, by checking the presence/absence of an occult blood portion, the present invention assists in early detection of colorectal cancer and allows a fecal occult blood test to be performed in a hygienic manner without burdening the user.
